Be it known that I, EDwARD G.;L AK, a

citizen of the United States, and a resident of Reno, in the county of Washoe. and State of Nevad-a, have invented certain'new and useful Improvements in Brush Grubbers, and Levelers, of which thefollowing is a H I I v nectron, as for, instance, double-trees when a team "is fused, or'av suitable hitch when a.

speoifioation, My invention 1s-an improvement in sage brush grubbers, and has for its object to provide a simple, easily. constructed, economical device 'of the character specified,

wherein an A-frame is provided adapted; to. be drawn through the sage brush, and provided with cutting blades on its inclined. V p g g y ure 1, that 'is ,with ,the side. end rearmost. Thus the rear end of each bladeextends slightly beyond the front end of the sucside for cutting or pulling up the brush.v

In the drawings:

V Figure l'isa top plan view.' of the improved grubber,

Figure 2 is alongitudinal section, V g z I Figure 3 is a transverse seotionjof the runner, r

Y Figures 4: and 5 are sections on thelines V Jr-4L and 55 of Figure 1.

In the present embodiment of the invention, an A-frame is provided, whichinthe present instance, is formed. from T rails. The frameis substantially \l-sh-aped in out line and consists of converging side members 1 and connecting cross members 2 The Side members 1 are secured together at their front ends, and the cross bars 2 rest upon the side members at their ends, and are secured thereto-by angle'brackets- 3, the said bracketsbeingboltedto the bal se flanges of the crossmembersganti to the webs of the side membersby bolts; and

nuts 4:.

A central longitudinally, extending member 5 is seated on the cross members, and is secured to the end cross members by bolts 6 and 7, the bolts 7 extending downwardly through the forward cross member 2 and being engaged by a nut 8 below the same.

A guide andrunner 9 is secured to the two rear cross bars 2 below the same and at the longitudinal center of the frame, by means of bolts 10 as shown, the said runner being made from an I-bear'n having its lower flanges cut away as clearly shown in Figure 3. The free-edge of this guide and runner extends well below the underface of the side members 1 of the frame, and it will be evident that when the frame is drawn along the round in a mannerrto be presently described, the guide and runner will by its engagement l the ground hold the a frame brush. a

Draft c onnectlng apparatus indicated-at from being deflected laterally by stiff 11 issecured to; the side members their connected: ends, and any suitable draft mechanlsm maybe connected with this conceeding' blade, the distance being in accord-I ance. with conditions, preferably 1% to 2 inches.

Uprights 13 are securedto the inner faces of the treads and webs of the side members 1. The ball of the tread is cut away to rece ve thenpr ghts, the arrangement being suchthat the uprights fit closely againsttheweb of therail in the notched or cutaway portions of the tread;

Thestandards are bolted: to the side mem "r. *orrrcs; 1

bers as indicated at 14c, and, they are con- 1 nected attheir tops andnear their bottoms by metallic plates 15.. The forward standard at eachYside is just behind the forward cross bar 2,1and an angle lateldis secured. to' theforwardly exten the bruslnand prevents it frombecoming caught atthe fronttof the frame .oper iti n,"th e name isdrawn the brush in any suitable or desired manner, with the guide and runner 9 engaging V 7 ing" ends of the plates15. This plate 16 acts as a fender for throughin the ground. The blades strike the brush and shear the same close to the surface of the ground. The runner 9 prevents the frame being shoved aside, by heavy brush and causes it to be moved straight ahead so that the brush may be cut in swaths.

The blades are secured to the flanges of the side members by bolts and nuts 17.

In operation the cutting blades may not always shear the brush off entirely, but may I cut into body'of the brush and hold it, and

the wedge shape of the machine moving along ulls said unsheared brush out by the roots and leaves itin windrows at either side of the machine. A great quantity of the g brush 'iscut off but there is also a large portionwh'ich is pulled out by the roots.

I claim 1. A device of the character specified,

comprising an A-frame having series of blades at the underrsurface thereof and extending beyond the sides of the frame, eaclr blade having its cutting edge lying in a plane extending obliquely to the plane of the proximate side of the frame and being spaced from the latter and a gu'ide iand runner at the rear and center of the fra me, and extending below the frame to form a fin 0r vane 'for engaging within the ground w-henthe frame 1s drawn over the ground',

said frame having a super-structure providedwith a vertically disposed angular de-,

fleeting plate arranged at the front of the frame with the apex of the deflecting plate foremost. 7

2 A device'xof the character specified,

comprising an A-fra-me having series of blades at the under surface thereof-extending beyond the sides of the" frame, each blade having its cutting edge lying in a.

plane extending obliquelytoq the plane 0t 1 the proximate. side of the frame and beingspaced from the latter and a guide and run n'er at the rear and center of the frame, and extending below the frameto form a fin or vane for engaging within the ground whenthe frame is drawn over the ground,

' and'a vertically disposed angular deflecting 7 plate supported at the front of the-frame With the apex of s-aid deflecting plate foremost and substantially in the plane of said guide and runner.

3. A device er the character described comprising a, substantially V-shaped'fra-me including side members converging together at their forward ends, a seri'es of;

cutting blades carried by each side member with 'the'cutting-edge of each blade located laterally of'the 'side member and in a planerearward'ly divergent in respect to the plane of the side member, and an angular'deflecjting plate supported-on the frame at the forward end o'fth-e letter, said angular defleeting plate having the respective arm portions thereof -disposed "substantially in vertical alignment wth the corresponding sides of the frame.

44A device of the character described 7 comprising a substantially V-shaped frame including side members converging "to geth'e-r at their forward ends, aseries of cutting blades carried by each side member with the cutting edge 'of each blade located laterally ofthe side member and in'a plane rearwardly divergent in respectto' the plane of the side member, means atthe' forward end of the frame and in the longitudinal median line thereof forestahli'shing connec-- tion with a draft mechanism, andanan gular deflecting plate supported on the frame at the forward end of the latter, said angular defiectine platehaving the respective arm portions thereof disposed snbstan-z tially in vertical alignment wthrthe'corre sponding'sides ofythe frame, r

5; A device of the character described comprising a substantially if-shaped frame including side members; converging together at their forward endfs, a series of cutting blades carried by each side member with the cutting edge of each blade locatedlaterally of theside member and -i-n--a plane rearwardly divergent respect tothe plane of the side member, means at the forward end of the frame-and in the longitudinal median line thereof for establishingconnection with-ca draft mechanism, a depending guide at the rearward end ofthe frame and and in the longitudinal median-line thereof. for engaging a surface traversed by the EDWARD co r LEAK.
